Ethereum's Fast Confirmation Rule targets 13-second bridge times with 98% reduction: Ethereum Foundation

Ethereum is moving forward with a Fast Confirmation Rule (FCR) designed to dramatically accelerate bridge times between Layer 1 and Layer 2 solutions, as well as exchange deposits. The mechanism targets completion times of approximately 13 seconds—a reduction of 80–98% compared to current timelines—and achieves this without requiring a hard fork to the network.

The FCR leverages attestations rather than blocks to verify transactions, representing a shift in how Ethereum handles cross-layer confirmation speed. This proposal aligns with broader Ethereum roadmap efforts to reduce finality times and slot durations, part of a longer-term vision to make the network faster and more efficient for users and institutions.
